It outputs an analog voltage linearly proportional to sensed current, making it ideal for microcontroller-based projects. Use it to monitor power consumption, protect circuits, or build smart energy meters.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCurrent Range\u003c\/td\u003e\n\u003ctd\u003e±5A\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensitivity\u003c\/td\u003e\n\u003ctd\u003e185 mV\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eAnalog (0–5V)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBandwidth\u003c\/td\u003e\n\u003ctd\u003e80 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n\u003ctd\u003e2.1 kVRMS\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-bench-power-supply-monitor\"\u003eOvercurrent protection circuit for a bench power supply\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eReal-time current monitoring dashboard with Arduino and OLED\u003c\/li\u003e\n  \u003cli\u003eBattery charge\/discharge logger for solar setups\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-motor-stall-detection-system\"\u003eMotor stall detection in robotics projects\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eWorks with any 5V microcontroller that has an analog input, including Arduino Uno, Nano, and ESP8266 (with ADC). Connect to 3.3V boards via voltage divider, though full 5V scale ensures best resolution. Commonly paired with I2C ADC modules for 3.3V systems.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 5V, GND to common ground, and OUT to an analog pin. The module passes current through screw terminals; ensure load is within 5A. For noisy environments, add a small capacitor near the VCC pin to reduce ripple.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Uno?\u003c\/summary\u003e\u003cp\u003eYes, the ACS712 module works directly with Arduino Uno’s 5V analog inputs. Connect OUT to A0 and read the voltage to compute current.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow do I convert the analog output to current?\u003c\/summary\u003e\u003cp\u003eThe output voltage is 2.5V at zero current, with sensitivity 185 mV\/A. Subtract 2.5V from the reading, then divide by 0.185 to get current in amperes.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I measure AC current with this module?\u003c\/summary\u003e\u003cp\u003eYes, the ACS712 can measure both AC and DC. For AC, you’ll need to sample quickly enough to capture the waveform and calculate RMS.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
